}
```

Source: https://github.com/radgeek/feedwordpress/blob/master/readme.txt

This PHP code snippet demonstrates how to conditionally display syndication information within a WordPress theme's template files. It's useful for showing bylines and original source links for syndicated posts.

```php
<?php if (is_syndicated()) : ?>
    <p class="byline">This post by <?php the_author(); ?> originally
    appeared at <a href="<?php the_syndication_source_link(); ?>"><?php
    the_syndication_source(); ?></a>.</p>
    <?php else : ?>
    <p class="byline">By <?php the_author(); ?>.</p>
    <?php endif; ?>
```
